Introduction

Disconnecting Battery. Internal Prereq.

Parts

No parts required.

Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board. It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

Is this step of removing the battery connector required?

yes - as with disassembly of any electronic component you have to remove any power source. You don't want to accidentally turn the Mac on

Sooo the track pad is under the battery...you kind of have to remove it to get to the track pad.

This step is not really required. Apple does not recommend it.

My Battery does not get recognized after i disconnected it, screw this site!

Did you properly ground yourself to the case before putting the spudger to the connector/logic board? Did you use a spudger or something else that is non conductive...or did you use a flat blade metal screw driver instead and compound your error by not grounding yourself before touching the logic board? All kinds of variables here but the bottom line is iFixit provided you a guide to fix your computer. Lots of others have followed this guide without trouble. Your battery issues are not their fault. They did say this guide was moderate difficulty...maybe it's just a little beyond your skill level. We should all know our limits!

Rather than be careful of the corners of the connector i would say don't use the spudger anywhere near the corners. While the corner looks like the obvious place to begin to pry it up from, it will break. Levering from the sides as the instructions suggest works well.

wonder why apple does not recommend it?!

I would recommend it, one careless short and the whole board is dead......

simply remove the battery rather than disconnecting the cable

What do you mean by "remove the battery"?

Don't know what the deal is with the battery, but this IS a necessary step to keep from frying the logic Board if you accidentally touch something and short it out. I did this step every time during my troubleshooting and The battery was ALWAYS recognized by the system the next time I turned the MBP on. So be safe and don't fry your logic board in the process...

Prying the battery connector off does not take much force. I did exactly what the guide suggested (walked it off back and forth) with the spudger without any problems. Just be very gentle, much like with anything inside laptops, they are very fragile and need to be worked with carefully. A+ instructions, battery replacement was a success.

Installed/upgraded 4gb RAM to the system maximum 16gb and installed a 500 gb SSD today....DID NOT disconnect the battery cable....no issues at all when I powered back up. Then did a clean install of OSX Yosemite....next I used a time machine backup to put all my stuff back on the new HD. From start to finish it took about 4 hours. Macbook boots up right at 16 seconds now.

Easiest to use two spudgers, one on each short end, I found.

I took off th Airport /Bluetooth connectors but the number J3 connector is broken and so where can i buy J3 connecter for the Airport/bluetooth board

Its a lot easier and safer (corner wise) to pry it using the flat side of the black spudger directly in front of the connector (don't go/use the corners) very easily you will be able to pry it further by inserting the spudger into a better and thicker plastic section of the connector

DON'T remove the Battery Cable, you risk the battery NOT being recognised when you start the Mac up again, or breaking it!! More to the point, APPLE DOES NOT RECOMMEND THIS, so don't do it! I Installed 2x 8GB ( 16Gb total) of Crucial Mac RAM at 1333Mhz for my Late 2011 MacBook Pro, and it works beautifully, fully recognised and working well. I followed these instructions, but as Apple didnt recommend disconnecting the battery, I skipped this step, and as well as taking less time, nothing was damaged or broken, and everything works perfectly!!! Just make sure that you DISCHARGE ALL STATIC ELECTRICITY FROM YOUR HANDS, by touching a metal surface in the Mac. Apple recommends the edge of the Optical Disk Drive ( Big silver thing ) before touching any parts. Also, Take care removing the RAM out of its packet, DO NOT touch the Gold connectors, and hold the RAM by the edges. Finally, be PATIENT, GENTLE and it should all go perfectly. I managed it first time, with no technical ability, so follow my advice. Good luck!

Followed the tuto Step by step. Disconnected the battery (quite easily).

No problem when I lit the Mac on again. Battery's here, date's right.

Switch off your Mac and continue without disconnecting the battery. Don't know how it will switch on by itself.

Mfernandez - Reply

This comment made me think that disconnecting the battery was no point at all, because really - how would the computer be able to switch on by it self. So... I had my mac flipped around and was fiddling with the last part of the guide when I all of a sudden hear the start up sound! Don't know how and why it did. I turned it around with it guts open and guts hanging out. Screen was on. I forced it to shut down by keeping the power button down. Turned it back and first thing removed the battery cord.

Luckily the computer started up just like normal. But hearing that sound was just too scary.

BTW I had been cautious to de static myself multiple times.

Definitely do this step. It's an easy disconnect anyway and also easy to reconnect later.

Stephen Smith - Reply

I removed the battery cable for the repair. When I plugged in the MagSafe adapter after the repair, the Mac turned on automatically without pressing the power button and I was a bit worried, but after a restart everything worked fine again. I did have to reset date and time in Preferences. The battery was recognized OK.

Okey, I skipped this battery disconnection part. Did not do anything like this before in my life, changing the cable was super easy!

Marijke de Vries - Reply

The official Apple guide to replacing the RAM says nothing about disconnecting the battery but it does recommend touching metal inside to discharge static. https://support.apple.com/en-us/HT201165

I always do this when working on MacBooks (over ten years) and it never caused an issue. Don’t worry about this step as removal of the battery connector is simple. This particular connector is pretty much goof-proof as it won’t break. I’m fairly aggressive and just pop it off whenever I’m working on the Macbook Pro.

Hello!

Do I really need to use a spudger tool? Can’t I just use like two plectrums for guitar? xD

Bend the battery cable slightly away from its socket on the logic board so it does not accidentally connect itself while you work.

What are the changes of it broke when i bend it?, after i disconect it does not work anymore

The guide worked perfectly, as it has in the past (our family has three Mid-2012 Macbook Pros that have been separately upgraded with RAM and SSD).

The PH00 screwdriver fit perfectly.

One note on getting the screws to seat easily and thread perfectly...always turn them gently a couple turns to the left (CCW or Anti-Clockwise) until you hear a small click. That's where the threads will grab. Works with any screw, but when threads are fine, this will help ensure that the screw is at the correct angle and will grab and seat perfectly.

Great guides. Thanks!

Got RAM in but only one slot is working and now I can't remove! The RAM won't pop up like before and tabs don't seem to do anything. Please advise.

I put some tape between the connector and socket while working on the drive.

Stephen Smith - Reply

That's a good tip

Anrothan -

Followed the advice and right as I was installing the replacement fan , the socket broke right off the motherboard.

One other note: The screw heads fit flush with the curvature of the case -- which means that they aren't exactly horizontal. In other words, they aren't perpendicular to the table that the computer is resting on. Don't try to force them straight in vertically, because you'll risk cross-threading them. (nearly ruined one screw hole myself!)

does the battery connection need to be removed? I only ask as other videos etc have not shown this step.
